Nesom 2925 Hartwood Drive Fort Worth, TX 76109, USA www.guynesom.com ABSTRACT A taxonomic overview is provided for Fraxinus profunda –– including a nomenclatural summary with lectotypes designated for F. profunda and the synonymous F. michauxii , an updated morphological description including a comparison with F. pennsylvanica , and a county-level distribution map. Geographically disjunct records for F. profunda in distinctly inland localities (Mississippi and Alabama) are documented; far-inland records from Tennessee and North Carolina were based on collections of F. biltmoreana . KEY WORDS : Fraxinus profunda , F. michauxii , F. pennsylvanica , Oleaceae Fraxinus profunda occurs primarily along the Atlantic and Gulf coasts into peninsular Florida and in drainages of the Mississippi River and in the Ohio River basin (Little 1977; McCormac et al. 1995). At the northwestern corner of its range, it occurs in bottomlands of the Kankakee River (vPlants 2010), an Illinois/Mississippi River tributary. Limits of the northern range of the species (Michigan, Ontario) have recently been documented in detail (McCormac et al. 1995; Waldron et al. 1996). The trees consistently grow in river swamps and floodplains, especially those seasonally inundated, freshwater tidal wetlands, commonly with bald cypress, swamp cottonwood, and water tupelo. In Illinois, Indiana, Ohio, and northward, they often are found in wet woods and swampy depressions in upland woods as well as till plains and clay lake plains of post-glacial lake beds. Based on the map from Little (1977), Harms (1990) noted that the range of Fraxinus profunda is “quite discontinuous,” but addition of recent records shows a more continuous range (Fig.

  • Well-Known Plants in Each Angiosperm Order
    Well-known plants in each angiosperm order This list is generally from least evolved (most ancient) to most evolved (most modern). (I’m not sure if this applies for Eudicots; I’m listing them in the same order as APG II.) The first few plants are mostly primitive pond and aquarium plants. Next is Illicium (anise tree) from Austrobaileyales, then the magnoliids (Canellales thru Piperales), then monocots (Acorales through Zingiberales), and finally eudicots (Buxales through Dipsacales). The plants before the eudicots in this list are considered basal angiosperms. This list focuses only on angiosperms and does not look at earlier plants such as mosses, ferns, and conifers.

  • Honey Locust: Identification and Management by James M
    Honey Locust: Identification and Management by James M. Locke NF-SO-11-01 Honey locust (Gleditisia triacanthos L.) is a native tree species also known as honey-shucks locust, sweet-locust, three-thorned acacia, sweet-bean or thorny locust. It has a natural range that extends from central Pennsylva- nia to South Dakota to southeastern Texas to Alabama. This range was probably expanded by Native Ameri- cans, who used the wood, pods and seeds for several purposes, and later by wildlife and ornamental plantings. It is best adapted to moist, bottom- land soils, but can survive on a wide variety of sites. Honey locust is often one of the first trees to occupy an area that was once woods, was cleared and is reverting back to woods. It is a moderately fast growing tree that has proven to be hardy and tolerant of drought conditions and saline soils. Identification The honey locust is a leguminous tree or a member of the Pea family (Fabaceae). At maturity, trees may be 70 to 80 feet tall and 2 to 3 feet in diameter at breast height, although under ideal conditions they may be up to 140 feet tall and 5 to 6 feet in diameter at breast height. The bark is medium to dark gray or brown with elongated plate-like patches separated by furrows. These plate-like patches may produce warty growths resulting in a rough trunk texture. Honey locust leaf arrangement is alternate, and its leaves are doubly4 Top photo: A mature honey locust tree growing on an upland site.

While this insect causes significant dam- age there are many other pests that can disfigure honeylocust. Some of the common pests include honeylocust pod gall midge, mimosa webworm, calico scale and honeylocust spider mite. If you need to treat for any of these insects on honeylocust keep in mind broad spectrum insecticides can kill natural enemies of the honeylocust spidermite and result in future mite outbreaks. Take that into consideration when reviewing your management options, and if treatment options include horticultural oils, insecticidal soap, spinosad or Bacillus thuringiensis choose one of these. They have little or no impact on spider mites’ natural enemies. Honeylocust Plant bug (Diaphnocoris chlorionis) One of the great difficulties in controlling this pest is that it be- comes active almost as soon as the tender leaves begin to emerge. The insects initially hang out within folded leaves where they are well camouflaged and can be easily overlooked. Hosts Honeylocust only Description and Life Cycle; The Honeylocust plant bug has one generation per year. It over winters as eggs in the bark of 2-3 year old twigs. As the buds begin to open, the eggs hatch, and the pale green nymphs crawl onto unfolding leaflets where they are subtly visible. They have short wing buds that don’t reach the ends of their bod- ies.

  • 3K 45 Attack of the Urban Forest Eaters.PMD
    The attack of the urban forest eaters: how a dedicated and educated group of volunteers is responding to the invasion of Asian long-horn beetles and gypsy moths in Chicago Julie Sacco Abstract The concept of biodiversity is largely unfamiliar to and unembraced by the general public. The overdeveloped nature of urban habitats and the underdeveloped awareness of their human inhabitants lead to a perception by the general public that one tree is as green as the next, and that most insects should be squashed on sight. TreeKeepers are trained citizen foresters who volunteered for the Openlands Project to help maintain the health of Chicago’s green infrastructure. In a unique partnership with Chicago’s Bureau of Forestry and the Chicago Park District, TreeKeepers serves as a national model for interagency cooperation, public-private partnerships, and advocacy on behalf of the urban forest. Since 1991, over 500 people from almost every neighborhood in Chicago have taken the 7-week TreeKeeper training course to learn basic arboriculture skills including tree identification and physiology, soils, planting and pruning techniques, tree disease, and insect problem recognition. Tree Keepers volunteer on workdays in different parks and along Chicago’s boulevards to help city crews with tree maintenance and other greening activities. In January of 1998, TreeKeepers were invited to an informational workshop presented by the Illinois Department of Agriculture (IDA) and Chicago’s Bureau of Forestry (CBOF) about the spread of the gypsy moth (Lymantria dispar) in Chicago, and on monitoring efforts being launched later in the year. Attendees, including CBOF staff, learned that the gypsy moth had been defoliating its way westward since its accidental release from a lab in Medford, Massachusetts, in 1869.

  • Intraspecific Variation in Fraxinus Pennsylvanica Responses To
    New Forests (2015) 46:995–1011 DOI 10.1007/s11056-015-9494-4 Intraspecific variation in Fraxinus pennsylvanica responses to emerald ash borer (Agrilus planipennis) 1 1 2 J. L. Koch • D. W. Carey • M. E. Mason • 3 1 T. M. Poland • K. S. Knight Received: 1 December 2014 / Accepted: 10 June 2015 / Published online: 21 June 2015 Ó Springer Science+Business Media Dordrecht (outside the USA) 2015 Abstract The emerald ash borer (EAB; Agrilus planipennis Fairmaire) is a bark and wood boring beetle native to east Asia that was first discovered in North America in 2002. Since then, entire stands of highly susceptible green ash (Fraxinus pennsylvanica Mar- shall) have been killed within a few years of infestation. We have identified a small number of mature green ash trees which have been attacked by EAB, yet survived the peak EAB infestation that resulted in mortality of the rest of the ash cohort. Adult landing and feeding preference bioassays, leaf volatile quantification and EAB egg bioassay experiments were used to characterize potential differences in responses of these select ‘‘lingering’’ green ash trees relative to known EAB susceptible controls. Three selections were identified as being significantly less preferred for adult feeding, but no specific leaf volatile profile was associated with this reduced preference. Egg bioassays identified two ash selections that had significant differences in larval survival and development; one having a higher number of larvae killed by apparent host tree defenses and the other having lower larval weight. Correlation and validation of the bioassay results in replicated plantings to assess EAB resistance in the field is still necessary.
